KE300A-11 Series High Power And High Protection Inverter According to the application characteristics of 710-1200KW high-power motors, a special product developed which is using parallel dynamic current sharing technology of IGBT modules. The unique heat dissipation design fully meets the heat dissipation problem of high-power frequency conversion, and guarantees cost performance at the same time. Features of KE300A-11 Series High Power And High Protection Inverter • Easy to install and debug • Solid EMC design, unique radiator shape. • Adopt modular design • The main control system uses 32-bit high-speed DSP, integrated PG-free vector control, V/f control, and torque control. • The optimized motor parameter identification model can effectively reduce the sensitivity to motor parameters and make self-learning more accurate. • High starting torque: 150% of starting torque can be provided when it is at 0.5Hz; • Fast dynamic response: Under the vector control mode without PG, the dynamic response time is less than 20ms; • Built-in PID regulator can easily form a closed-loop control system for process quantities such as temperature, pressure and flow. • It has automatic fault reset and power-off reset functions to ensure continuous production and production efficiency. • Perfect protection functions: overvoltage/under-voltage protection, inverter overheat protection, ground fault protection, short circuit protection, overcurrent protection, overload protection, etc.
